Zinc is an important additive for those driving the car hard. It helps protect the bearings when you loose oil supply in a turn as well as extended wear. My brother had about 10k miles on his Cobra when he swapped to synthetic Without zinc. His first time out he blew his bearings in the bottom end. He pulled the pan off (in car) swapped bearings, went back to dino oil with zinc and put another 20k miles (with many track and drag events) before pulling it to put a larger disp engine in. The engine is still ready to go now.
